process.c: tmp buffer instead of alloca

* process.c (OBJ2UID1, OBJ2GID1): separate from OBJ2UID and
  OBJ2GID respectively, need given buffers.

* process.c (OBJ2UID, OBJ2GID): no longer need PREPARE_GETPWNAM
  and PREPARE_GETGRNAM.

* process.c (obj2uid, obj2gid): use tmp buffer instead of alloca
  to get rid of potential stack overflow.

process.c: expand buffer on ERANGE

* process.c (obj2uid, obj2gid): now getpwnam_r() and getgrnam_r()
  may need larger buffers than sysconf values, so retry with
  expanding the buffer when ERANGE is returned.
